Overview of MAX3082EEPA+
The MAX3080EMAX3089E are ±15kV electrostatic discharge (ESD)-protected, high-speed transceivers for RS-485/RS-422 communication that contain one driver and one receiver. These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The MAX3080E/MAX3081E/MAX3082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 115kbps. The MAX3083E/MAX3084E/MAX3085E offer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX3086E/MAX3087E/MAX3088Es' driver slew rates are not limited, making transmit speeds up to 10Mbps possible. The MAX3089E's slew rate is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a single three-state driver. All devices feature enhanced ESD protection. All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model.
